tendon guiding forceps

Abstract

The invention provides tendon guide forceps. The tendon guide forceps comprise forceps for clamping a fractured tendon, the tail ends of the forceps are connected with one end of a traction tube, a handle for controlling the forceps to be opened and closed is arranged at the other end of the traction tube, and when the forceps are closed, the front end of a fixed forceps body forming the forceps is located in front of the front end of a movable forceps body. The two forceps bodies which are staggered front and back enable the forceps to move forwards for a certain distance when reaching the tendon, so that the front end of the fixed forceps body is inserted into a gap between the tendon and the tendon sheath; at the moment, an operator can obtain a clear hand feeling to judge that the fixed forceps body is in place, then the forceps are opened through the handle to continue to move forwards to enable the tendon to be located between the fixed forceps body and the movable forceps body,and at the moment, the closed forceps bite the tendon to lead the tendon out of the tendon sheath. In this way, the tendon can be guided quickly and accurately, medical staff can determine the state of the forceps through the hand feeling in the operation process, repeated attempts are not needed, the searching and clamping frequency is reduced, the operation time is shortened, and harm to a patient is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tendon guiding forceps. Background technique [0002] Injury to the tendon is common during surgery, as the tendon often retracts when it ruptures. In particular, the rupture of the flexor tendon in zone II will retract into the palm or even the carpal tunnel. In order to ensure the need for minimally invasive surgery to facilitate postoperative recovery, it is necessary to blindly explore the tendon with tendon guide forceps along the tendon sheath. [0003] Existing related designs in the prior art, i.e. Chinese patent documents CN2549912Y , which discloses a tendon guiding forceps, which includes a traction part and an occlusal part that can be opened and closed. The occlusal part is composed of two pliers heads with the same structure. It is difficult for medical personnel to judge whether the occlusal part has reached and occluded the tendon, and blind clamping failure...

Problems solved by technology

[0003] Existing related designs in the prior art, i.e. Chinese patent documents CN2549912Y , which discloses a tendon guiding forceps, which includes a traction part and an occlusal part that can be opened and closed. The occlusal part is composed of two pliers heads with the same structure. It is difficult for medical personnel to judge whether the occlusal part has reached and occluded the tendon, and blind clamping failure is prone to occur, requiring repeated attempts to probe in and out. In the process, it is easy to cause secondary damage to the tendon and tendon sheath, and it will also prolong the operation time.
